The warranty for replacement devices and used devices only covers the modules/components and warranty services stated in the invoice.
In the case of control units that do not correspond to the original condition or have not been opened, we will carry out repairs to the best of our knowledge at the express request of the customer. In such a case, we reserve the right not to grant or restrict a guarantee of perfect functioning.
If a device is sent to us again for complaint and inspection and shows no defect, we calculate our expenditure (inspection lump sum / cost estimate / shipping costs etc.). If a device should not function after the repair, we reserve ourselves the right to the examination and rework. If the control unit cannot be repaired during the 2nd repair attempt, you will receive back the repair price for the corresponding unit. Devices must be returned to us before the repair price is refunded.
All other costs incurred such as shipping etc. will not be reimbursed. We will then calculate our cost estimate in any case. We do not take over costs, which result from installation and dismantling, as well as for consumables. With sporadic errors the danger lies with the customer, i.e. here the function can be proven sometimes only after reassembly in the vehicle and longer test drive. Consequential damages are generally not acknowledged.
